Problems solved by technology

The value of the output wavelength λ of the resonant cavity is related to the viewing angle θ. When the viewing angle θ increases, λ decreases, and the output light is blue-shifted and the intensity is weakened. Therefore, the top-emitting OLED display will have a large JNCD problem.

Abstract

The present invention relates to the field of display technology, and discloses an organic electroluminescent display device. The organic electroluminescent display device includes a substrate, an anode arranged on the substrate, and an organic light-emitting layer arranged on the side of the anode away from the substrate. The optical adjustment layer used to adjust the light angle emitted by the organic light-emitting layer in the edge area of ​​the light-emitting path of the organic light-emitting layer. Greater than the refractive index of the optical adjustment layer, without changing the light transmission path under the normal viewing angle, the deviation angle of the outgoing light under the large viewing angle is increased, and the light transmission path under the large viewing angle is changed, thereby ensuring the positive viewing angle. Correct the chromatic coordinates under the large viewing angle at the same time, so as to reduce the chromatic aberration under the large viewing angle.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display device. Background technique [0002] Currently, top-emitting organic electroluminescent displays (OLEDs) generally use electroluminescent devices with microcavity structures. The microcavity effect is produced by multi-beam resonance, which shows that the spontaneous emission of the luminescent material at the resonance wavelength is enhanced, and the spontaneous emission not at the resonance wavelength is suppressed. The value of the output wavelength λ of the resonant cavity is related to the viewing angle θ. When the viewing angle θ increases, λ decreases, the output light is blue-shifted, and the intensity is weakened. Therefore, the top-emitting OLED display will have a large JNCD problem. Contents of the invention [0003] The invention provides an organic electroluminescent display device, which can correct the color coordinates a...
